GD2 CAR T Cells in Diffuse Intrinsic Pontine Gliomas(DIPG) & Spinal Diffuse Midline Glioma(DMG)

Eligibility Criteria

• 1. Bulky tumor involvement of cerebellar vermis or hemispheres (pontocerebellar peduncles involvement is acceptable), or thalamic lesions that in the investigator's assessment place the subject at unacceptable risk for herniation.
• 2. Clinically significant swallowing dysfunction/dysphagia or prominent medullary dysfunction, as determined by the clinical investigator.
• 3. Current systemic corticosteroid therapy.
• 4. Ongoing use of dietary supplements, alternative therapies or extreme diets or any medication not approved by the investigators
• 5. Prior CAR therapy.
• 6. Prior GD2 antibody therapy
• 7. Uncontrolled fungal, bacterial, viral, or other infection. Previously diagnosed infection for which the patient continues to receive antimicrobial therapy is permitted if responding to treatment and clinically stable.
• 8. Diagnosed ongoing infection with:
• * HIV,
• * Hepatitis B (HBsAg positive) or
• * Hepatitis C virus (anti HCV positive). A history of hepatitis B or hepatitis C is permitted if the viral load is undetectable per quantitative PCR and/or nucleic acid testing.
• 9. Clinically significant systemic illness or medical condition (e.g. significant cardiac, pulmonary, hepatic or other organ dysfunction), that in the judgement of the principal investigator is likely to interfere with assessment of safety or efficacy of the investigational regimen and its requirements.
• 10. Women who are pregnant or breastfeeding.
• 11. In the investigator's judgment, the subject is unlikely to complete all protocol required study visits or procedures, including follow up visits, or comply with the study requirements for participation.
• 12. Known sensitivity or allergy to any agents/reagents used in this study.
• 13. Primary immunodeficiency or history of autoimmune disease (e.g. Crohns, rheumatoid arthritis, systemic lupus) requiring systemic immunosuppression/systemic disease modifying agents within the last 2 years
